Customer Forms

Customer Registration Form

When a property is sold in New York City, the new owner must alert DEP to the transfer of ownership by completing a Customer Registration Form. This form provides DEP with the appropriate mailing information for future water and sewer bills.

New property owners must fill out this application and mail it to DEP at the address provided on the form. The form can be completed directly in the Adobe Acrobat Reader or by hand.

Refund and Transfer of Credit Application

Customers who have a credit balance on one of their water and sewer accounts may request that the credit be transferred to another property, account, or be refunded to them in the form of a check. Please be advised that all requests must be accompanied by proof of payment through cancelled checks and receipts.

To transfer or refund credit, please complete the Refund and Transfer of Credit Application and mail it to the address listed on the form.

Water and Sewer Exemption

Certain qualifying organizations may be entitled to an exemption* from water and sewer charges. Eligibility is dependent on several factors and interested parties should review and complete the required sections as indicated in the Application for Exemption from Water and Sewer Charges (accessible by using the link below). Please read the General Instructions carefully (pages 1 through 4), complete and return the Required Documentation Checklist (page 5), and complete, notarize, and return the Application (pages 6 and 7). All supporting documentation and required forms must be mailed or delivered to the address provided in the General Instructions on the form.

*Consumption less than 9,493 CCF per year will result in a full exemption of water and sewer charges for the property. If consumption is between 9,494 and 19,053 CCF, the property will receive a partial exemption and charges for the property will be billed at ‘one half’ the total consumption. If consumption exceeds 19,053 CCF per year, the property will receive no reduction and will be billed at the full rate for the total consumption.

Election of Metered Billing Form for Multi-Family Properties with Four or More Residential Units

Owners of multi-family dwellings with four or more units billed on a fiscal (annual flat-rate) basis can elect to switch to metered billing if they determine it to be financially advantageous. Please be advised that DEP cannot advise customers in this matter.

All conversions to metered billing are final and cannot be reversed once completed. To switch to metered billing, owners must complete and mail an Election of Metered Billing Form to the address listed on the form.

Wastewater Allowances

Wastewater Allowances—for Evaporative Cooling Towers and for Standard Wastewater Allowances—may be available for certain customers that are current on their water and sewer charges.

To qualify, a property must have a dedicated metered water supply that supplies a process that does not discharge all of its water into the wastewater system. Please review the regulations defined in the NYC Water Board Water and Wastewater Schedule, Part II, Section 7 for more information.
